I was born and raised in the Sout' Suburbs, and I would assert that Popolano's is out of the woods, being in Porter County, Ind., as its Web site notes. Never heard of it myself until just now. If you're looking for fried chicken, try White Fence Farm -- far southwest suburbs, but at least in the state. Dell Rhea's would be pushing the upper limits.
Speaking of which: While the Country House offers a fine burger, I don't consider Clarendon Hills a South Suburb -- it's a western suburb.
And I've never tried Simply Slices, but I would think Aurelio's and Palermo's would be more appropriate choices as representative of the south 'burbs. Alas, Vito & Nick's is just inside in the city limits and doesn't qualify, though it was my family's pizza of choice during my formative years.
Nick's is a good choice -- I ate there often while working down the street at the Reporter/Regional News ...
Just my thoughts as a native south suburbanite now exiled to Hoffman Estates ;)
